Analysis of powdered milk by PIXE (Proton Induced X-ray Emission); Analisis de leche en polvo por PIXE (Proton induced X-ray emission)

Abstract

The purpose of this work was to establish the conditions to analyze elements of Z>15 in powdered milk samples using the PIXE technique. Ten different commercial samples were analyzed: 2 full-cream, 3 half-cream and 5 for infant feeding. They were all purchased in Toluca City, Mexico. Thick targets were prepared and irradiated with 1.5 and 3 MeV protons beam in Mexico`s Nuclear Center Tandem Van de Graff Accelerator. The obtained data were analyzed by two computers programs. Iron, the reference element was analyzed by atomic absorption spectrometry. Concentrations of the following elements: phosphorus, chlorine, potassium, calcium, chrome, iron, cobalt, nickel, copper, zinc, bromine, rubidium, molybdenum and cadmium were evaluated. The concentrations of the first four elements were usually high, whereas those of the other elements remained in some ppm. The experimental conditions set up in this work were suitable for the analysis of powdered milk and can be applied to other organic samples (Author).
